JAR MILL MOUNTING Filed April 20, 1964 2 Sheets-Sheet 2 INVENTOR. FRANK MALACHOWSKI ATTORNEY United States Patent 3,228,544 JAR MILL MQUNTING Frank Malachowski, West Richfield, Ohio, assignor to The United States Stoneware Company, Tallmadge, Ohio,

a corporation of Ohio Filed Apr. 20, 1964, Ser. No. 361,001 3 Claims. (Cl. 214-340) This invention relates to an improved mounting for jar mills in which the spacing of the rollers which support one or more jars is adjustable to accommodate jars of diiferent diameters.

According to the invention, the driven roller is fastened permanently to the support of the mill rollers, as is usual at the present time. The other roller, which is an idler roller, is not permanently fastened to the support. It can be readily spaced a selected distance from the driven roller. This is made possible by providing pairs of keyhole openings in the support, for engagement by headed projections extending from the pillow block or other means in which the idler roller is supported. These pairs of openings are spaced different distances from the driven roller. For a jar of smaller diameter, the projections are engaged in openings nearer the driven roller; for a mill of larger diameter they are engaged in openings farther from the driven roller.

The invention is further described in connection with the accompanying drawings, in which:

FIGURE 1 is a plan view of the jar mill showing the mounting and two jars in operative position;

FIGURE 2 is a section on the line 2-2 of FIG- URE 1;

FIGURE 3 is an exploded view showing a mounting strip and a pillow block of the idler roller;

FIGURE 4 is a side elevation of the equipment shown in FIGURE 1; and

FIGURE 5 is an end elevation on the line 55 of FIGURE 4.

The mill comprises a driven roller 1 which is bolted by bolts and nuts 2 to the mounting strips 3 in which there are keyhole openings 5. The ends of the idler roller 7 are held in pillow blocks 8 which has studs 9 extending from its bottom. These studs are engaged in the keyhole openings. The spacing between the studs is the same as that between any two adjacent openings. The roller 7 is readily disengaged from the mounting strips 3 by sliding the studs from the narrow ends of the respective keyhole openings to the wider ends. The roller may then be replaced at any desired distance from the roller 1 by engagement of the studs in appropriate open- "ice ings. The jars 10 are of intermediate size so the roller 7 is mounted in keyhole openings an intermediate distance away from the roller 1. For smaller jars the rollers will be closer together, and for larger jars they will be positioned farther apart.

The roller 1 is driven by the motor 15 through a gearreduction device in the box 16, using the belt 18 and chain 19. The mounting strips 3 are fastened to any suitable support 25.

As readily seen, the roller 1 is permanently mounted at one end of the mounting strips. The idler roller 7 is placed any desired distance from the roller 1 by location in any pairs of keyhole openings 5 depending upon the size of the jar which is to be placed in the rollers. The roller 1 is driven by the motor and turns the jars, and the roller 7 is merely an idler roller.

The invention is covered in the claims which follow.

What I claim is:

1. A jar mill installation which comprises a support, a driven roller and an idler roller adapted for the support and rotation of a cylindrical jar when placed thereon, the driven roller being permanently attached to the support, rows of keyhole openings in the support with the larger portion of each opening nearer the driven roller than the smaller portion, and spaced identically in the respective rows, bearing means in which the idler roller is held, with a headed projection extending from the bottom of each bearing means engaged in one of said keyhole openings.

2. The installation of claim 1 in which pillow blocks at the ends of the second roller comprise the bearing means, and there are at least two studs in the bottom of each block with the head of each spaced from the block so that the stud is adapted to be engaged in one of the openings.

3. The installation of claim 1 in which there are at least two headed projections from the bottom of each bearing, and the distance between each two projections on both bearings is the same as the distance between each two openings in each of the rows thereof.
